本文通过纯水浸提煤炭中的重金属,模拟自然降水或人工喷淋对港区存放的煤炭淋溶作用,结果显示浸出液的pH略呈下降趋势,而Cu、Zn、Pb、Cd的含量全部在μg/L级别,远远小于《危险废物鉴别标准浸出毒性鉴别》GB5085.3-2007的标准限值,说明大量水浸情况下,浸出液对周遭环境危害较小,不足以按照危险废物处理。
本文通過純水浸提煤炭中的重金屬,模擬自然降水或人工噴淋對港區存放的煤炭淋溶作用,結果顯示浸齣液的pH略呈下降趨勢,而Cu、Zn、Pb、Cd的含量全部在μg/L級彆,遠遠小于《危險廢物鑒彆標準浸齣毒性鑒彆》GB5085.3-2007的標準限值,說明大量水浸情況下,浸齣液對週遭環境危害較小,不足以按照危險廢物處理。

Based on the pure water leaching of heavy metals in coal,imitating outdoor coal eluviated by nat-ural rainfall or artificial spray. The results show that the leaching liquid pH was slightly declining,and Cu, Zinc, Pb, Cd were inμg/L level, far less than the hazardous waste identification standard of GB5085.3-2007. It suggests that leaching liquid was less harmful to environment when coal was immersed by big amount of water.
